Ny standard for Box PC'er er nu ratificeret

Box PC'er bruges i alle mulige industrielle sammenhænge, men i modsætning til board-level computing-platforme er der ingen standardisering på området. Det ændrer PICMG-organisation på med ModBlox7 specifikationerne (in english).

PICMG, a leading consortium for the development of open embedded computing specifications, has ratified the ModBlox7 base specification. The first-of-its-kind specification addresses industry’s need for modular and interoperable embedded box PCs by defining a flexible mechanical architecture and 'units' that fit a 1.4-inch horizontal pitch (7 HP) form factor.

The ModBlox7 architecture removes expensive components like backplanes and shelf controllers to enable the creation of price-competitive systems even at low volumes. Up to 12 of the 7 HP units can be interconnected and mounted on walls, DIN rails, or inserted in a 19” sub-rack.

- With ModBlox7, we combine the advantages of modular standards like CompactPCI and CompactPCI Serial with the demands we see from box PC customers like cost sensitivity, small form factor, and low weight, explains Mathias Beer, CEO of Ci4Rail GmbH and member of the PICMG ModBlox7 working group.

- By combining all of this in a PICMG specification, ModBlox7 addresses the design requirements of our clients and avoids vendor lock in.

The building block architecture of ModBlox7

A typical ModBlox7 system consists of Power Units, Processing Units, and PCIe or USB 2.0/3.0 Input and Output Units (IOUs), each of which measures 1.4” or 7 HP wide. Units can also be extended in 7HP increments to 14 HP, 21 HP, and so on and remain compatible with the specification.

Power Unit blocks convert external supply voltage into a 12V internal voltage and connect to Processing Units via terminal wire-to-board or board-to-board connectors. Processing Units support an overall thermal design power (TDP) of up to 150W and interface with IOUs over high-speed board-to-board connectors.

While a minimum ModBlox7 system consists of just one Processing Unit and one Power Unit, they can support as many as four PCI Express-based or eight USB-based IOUs. For high-availability or safety applications, ModBlox7 systems can also be configured with redundant Processing Units or Power Units. The maximum number of slots supported in any ModBlox7 is 12.

- The ModBlox7 standard defines a direct board-to-board interconnect in a box format to realize cost-effective system solutions. Thanks to native support for redundancy, ModBlox7 is also recommended for high-availability solutions, says Bernd Kleeberg, CEO and Head of Sales at EKF Elektronik GmbH and chair of the PICMG ModBlox7 working group
